I have just recently renewed my Antivirus subscription approx 1 month back, I went through the process of uninstalling my 2011 product and successfully installed 2012 Antivirus Plus, all is working fine and no issues and happy with the way it is all running, but I now notice there is a free upgrade to the 2013 Antivirus Plus, is it worth the hassle of uninstalling it all AGAIN and setting up the 2013 version and maybe create problems or should I just stick with the 2012 version and maybe update next year to I assume the 2014 version when it is available. As far as detecting issues, viruses etc. is there any major changes that are worth the trouble of doing it all again after just not long setting up the 2012 version. Ie: is it neccessary to every year to have to update?
